BOLT AND RETAINER THEREFOR.

where they are subjected to such vibration that the nuts tend to loosenand retract on their bolts. 1

A further object is to provide a bolt and a retainer therefor adaptedfor use in places not readily accessible, which cannot be separated bychance and which, therefore, require no attention followingintroduction.

In describing the invention in detail, ref erence is had to theaccompanying drawings, in which Figure 1 is a side elevation of the boltwith the retainer applied thereto, said retainer being shown in frontend elevation;

Fig. 2 is a sectional end elevation of the bolt with the retainerapplied thereto, said retainer being shown in side elevation;

Fig. 3 is a view similar to Fig. 1 showing the retainer partly in topplan and partly in broken section; and

Fig. 4 is a View similar to Fig. 2, showing the retainer jaws occupyingthe positions assumed when the retainer is being slipped upon the bolt.

eferring to said drawings, 1 indicates the body of a bolt which isprovided at a suitable distance from its point with a reduced neckportion 2 defined. at its inner and outer ends by shoulders 3 and 4.Said neck portion is designed to receive thereon a clamp-likebolt-retainer of approximately C-shape. said retainer being formed of asingle piece of metal and consisting of a resilient band-like body 5terminated at opposite ends by jaw-like portions 6.

ln its operative position the retainer is disposed in closely embracingrelation to the neck portion 2 of the bolt. The body 5 of said retaineris of relatively greater thick ness than the depth of the annularchannel which is out in the bolt in producing said neck portion, and thejaw-11k portions 6 project a considerable distance away fromSpecification of Letters Patent.

the bolt. Obviously, therefore, the inner face of the retalner abutsagainst the adacent face of a wall or web constitutes a' bearing aga nstwhich the retainer seats and which positively prevents any withdrawal ofthe vice is facilitated by rounding the adjacent the resilientcharacterof the device, the jaws will resume approximately their normalrelative positions after application, but should'they not do so, theymay be readily drawn to such positions by means of a suitable tool. Eachof said aws has a hole 7 provided therein, said holes being in alinementwhen the jaws occupy their normal position and being adapted for thereception of a suitable pin, as 8. by means of which said normalposition of the jaws may be maintained.

What is claimed is to said channel, the body of said retainer being ofrelatively greater thickness than the depth of saidchannel, saidretainer terminating in jaws of greatly increased thickness providedwith rounded adjacent faces adapted to facilitate disposal of saidretainer within and removal of it from said channel, said retainer beingadapted to be sprung around said channel into a position in which saidjaws lie in engagement, and means for securing said jaws together formaintaining said retainer in position.

2. A bolt retainer comprising, in combination with a bolt providedadjacent to its point with a reduced neck portion defined at its innerand outer ends by shoulders, a clamp-like bolt-retainer of approximateC- shape formed of a single piece of metal and consisting of a resilientband-like body terminated at opposite ends by jaws, said body being ofrelatively greater thickness than the depth of said neck portion, saidjaws being considerably thicker than said body and having theiradjacentfacesrounded said retainer in position in said neck portofacilitate application of said retainer into tion. and removal from saidneck portion, said In testimony whereof,I afiix my signature retainerbeing adapted to be sprung over in presence of two subscribin witnesses.5 said neck portion into a position in which EDWARD A.
